United States Patent Otice 3,282,223 Patented Nov. 1, 1966 3,282,223HANDLE AND PUMP CONSTRUCTION Henry E. Karlrut, Baldwinsville, NY.,assignor to Henry l'l. Karlrut, Inc., a corporation of New .Hersey Filed.lune 26, i964, Ser. No. 378,318 8 Claims. (Cl. 103-148) This inventionrelates to a novel and useful handle and pump construction and morespecifically to a handle and pump construction adapted to be supportedfrom a removable can closure such as that disclosed in my copending U.S.application Serial No. 228,352, for Paint Applicator, filed October 4,1962, now U.S. Patent No. 3,192,554 `dated July l6, 1965. Further, thehandle and pump construction of the instant invention includes means bywhich paint within the can closed by the aforementioned closure may bepumped from within the can by means of the pump portion of the instantinvention which is disposed exteriorly of the associated can orcontainer.

The handle and pump construction of the instant invention is designed insuch a manner that a painter standing on the floor or on a raisedplatform or support such as a ladder may support the handle and the pumpconstruc tion of the instant invention with one hand, with theassociated paint can attached thereto, and a roller applicator in theother hand such as that disclosed in my above-mentioned copendingapplication with the handle and pump construction of the instantinvention being operable to pump paint from the associated can orcontainer into the reservoir of the roller application. In this manner,a painter can readily move about and maintain a constant supply of paintin the reservoir of the roller applicator thus allowing the painter,within limits of his endurance, to greatly increase his production.

The main object of this invention is to provide a handle and pumpconstruction specifically designed to be supported from a closure of apaint can or the like and including means by which paint or other liquidmay be pumped from the associated can while the latter is substantiallytightly closed by means of the removable closure cover associated withthe handle and pump construction.

Still another object of this invention is to provide a handle and pumpconstruction including structural components which may be readilymanufactured at a low cost from various kinds of available material.

Yet another object of this invention is to provide a handle and pumpconstruction in accordance with the preceding objects including meansfor attaching the handle and pump construction and its associatedclosure cover to an associated paint can or the like with a minimumamount of effort.

A final object of this invention to be specifically enumerated herein isto provide a handle and pump construction which will conform toconventional forms of manufacture, be of simple construction and easy touse so as to provide a device that will be economically feasible, longlasting and relatively trouble free in operation.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

FIGURE 1 is a perspective view of the handle and pump construction ofthe instant invention operatively associated with a closure cover andillustrated with its closure cover operatively mounted on a paint canfor closing the same and further including a -iieXible paint supply lineconnected to the outlet of the pump portion of the handle and pumpconstruction at its inlet end and to a roller-type of paint applicatorat its outlet end;

FIGURE 5 is a fragmentary vertical sectional view taken substantiallyupon the plane indicated by the section line 5-5 of FIGURE 3;

FIGURE 6 is a perspective view of the body member of the associatedpaint can closure; and

FIGURE 7 is a horizontal sectional view similar to that of FIGURE 3 butfragmentary in nature and on somewhat of an enlarged scale showing themovable jaw elements of the pump construction in different positions ofoperation.

Referring now more specifically to the drawings the numeral 10 generallydesignates a conventional form 0f paint can including a partial annulartop wall 12 of conventional design and an outwardly projectingreinforcing flange I4.

The numeral 16 generally designates a can closure cover such as thatdisclosed in the above-mentioned copending application. The body member28 of the closure cover 16 has a pair of slots 20 formed therein throughwhich a pair of ears 22 of the handle and pump construction 24 of theinstant invention are secured in order to secure the handle and pumpconstruction 24 to the body member 18 of the closure cover 16, theclosure cover 16 including rotatable cam means 16 coacting with abutmentmeans 1S on the body member 18 adjustably maintaining the cover 16 andbody member 1S in generally parallel spaced relation. The handle andpump construction 24 includes a channel-shaped body 26 including a pairof generally parallel legs 28 interconnected by means of a bight portion30. The legs 28 include a pair of extensions 32 and the terminal end ofeach extension 32 abuts against the upper surface of the body member 18and has the corresponding tab 22 supported therefrom. The channel-shapedbody 26 further includes an upper end wall 33 which is formed integrallywith and defines an angulated extension of the bight portion 30. Theupper end wall 33 includes a pair of opposite side downturned ilanges 34which embracingly engage the upper ends of the legs 28.

The upper end wall 33 has a forwardly opening notch 36 formed thereinand a stationary handle element 38 is supported from the body 26 bymeans of tabs or ear portions 40 formed integrally therewith and securedthrough corresponding slots 42 formed in the bight portion 30. A movablehandle element 44 is pivotally supported from the stationary handleelement 38 by means of a pivot pin 46 and has a generally U-shapedactuator 48 secured thereto adjacent the pivot pin 46.

The bight portion 30 has a centrally disposed opening formed thereindefined by a pair of laterally struck portions 50 which are suitablyapertured so as to define mounting lugs or ears. A pair of jaw elementplates 52 are provided and each includes a pair of generally paralleland apertured mounting ears 54 which are registrable with the ears orlugs 50. A pivot fastener 56 is secured through the ears or lugs 50 andS4 and thereby pivotally supports the jaw element plates 52 within thechannel-shaped body 26 for movement of the free ends of the platestoward and away from each other. The plates 52 include slightlybackturned end portions 60 which are engageable by the U-shaped member48 carried by the movable handle element 44. As the U-shaped member 48engages the portions 60, the base ends of the plates from which theportions 60 are supported are spread apart and the free ends of theplates 52 remote from the portions 60 are swung toward engagement witheach other.

The handle and pump construction 24 further includes a resilient tubularsection 64 disposed within and extending longitudinally of thechannel-shaped body 26 between the jaw element plates 52.

A pair of fittings 66 and 68 are secured in the opposite ends of theresilient tubular section 64 and include valve seats 70 and 72respectively, which face down stream and have ball check valves 74 and76 operatively associated therewith. The ball check valves 74 and 76 areretained in position within the counterbored portions 78 and 80 of thefittings 66 and 68 by means of retaining elements 82 and 84,respectively. The retaining elements 82 and 84 are frictionally securedwithin the corresponding counterbored portions of the fittings 66 and68. Each of the retaining elements comprises an elongated platelikemember of a width slightly less than the inside diameter of thecorresponding fitting and endwise inserted therein behind thecorresponding check valve. The ends of the plate-like members 82 and 84remote from the corresponding check valves have endwise outwardlyopening notches 85 formed therein centrally intermediate the oppositeside edges of the plate-like members and defining a pair of endwiseprojecting legs 87 on each platelike member. The free end portions ofeach pair of llegs 87 include terminal end portions 89 bent towardopposite sides of the medial plane of the corresponding plate-likemember, the remote corners of each pair of terminal end portions 89being disposed in frictional engagement with the adjacent inner surfaceportions of the corresponding fitting.

The fitting 66 has the outlet end of an inlet line 86 secured theretoand the fitting 68 has the inlet end of an outlet line 88 securedthereto. The inlet end of the inlet line 86 projects downwardly throughthe tubular fastener 90 by which the closure member 92 of the closurecover 16 is pivotally supported from the body member 18 and ispositioned to receive paint from within the can and also serves toretain the lower end of the resilient tubular section 64 within the body26. The outlet end of the outlet line 88 is communicated with thereservoir portion 94 of the roller applicator generally referred to bythe reference numeral 96 and is therefore operable, upon actuation ofthe handle and pump construction 24, to supply the roller applicator 96with paint from within the container 10, the upper end of the resilienttubular section 64 being retained within the body 26 by means of afriction fit of the tting 68 within the notch 36.

It may be seen that the legs 28 of the channel-shaped body 26 defineabutments engageable by the jaw elements 52 to limit movement of thefree ends of the jaw elements 52 away from each other. Accordingly, itmay be seen that the movable handle element 44 may be urged toward thestationary handle element 33 so as to force the U- shaped member orportion 48 between the portions 60 carried by the jaw elements 52. Thisoperation will of course swing the free ends of the jaw elements 52toward each other and thereby clamp the resilient tubular section 64between the jaw elements 52.

Deformation of the resilient section 64 in this manner will cause aportion of the liquid disposed therein to unseat the valve element 76from the seat 68 and to pass upwardly into the outlet line 88 andsubsequently into the reservoir 94 of the roller applicator 96. As thehandle element 44 is allowed to swing away from the handle element 38,the ball valve element 76 will again seat on the seat 68 and the partialvacuum created within the resilient tubular section 64 will cause theball valve element 74 to move upwardly away from the seat 70 and fluidor paint from within the container 10 to be drawn upwardly IIO the.resilient tubular section 64 through the inlet line 8 6,

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be restored to, falling within the scope of the invention asclaimed.
